WATER-LIFT.

Specification of Letters Patent.

Patented Sept. 14, 1909.

Application filed May 2, 1908. Serial No. 430,443.

I 0 all whom it may concern:

Be it known that I, FRANKLIN OSCAR DE HYMEL, a citizen of the UnitedStates, and a resident of San Antonio, in the county of Bexar and Stateof Texas, have invented certain new and useful Improvements inVVater-Lifts, of which the following is a specification.

My invention is an improvement in water lifts and consists in certainnovel constructions and combinations of parts hereinafter described andclaimed.

Referring to the drawings forming a part hereof Figure l is a centrallongitudinal sec-.

tion of the improved lift showing the piston in one position. Fig. 2 isa similar view showing the piston in another position. Fig. 3 is acentral longitudinal section of the cylinder of the lift, Fig. 4 is adetail View of the piston and disk valve, and Fig. 5 is a section on theline 5-5 of Fig. 4.

The present embodiment of my invention, comprises a cylinder A, a casingB, a piston C, and a valve D.

The cylinder A is of equal cross section throughout, and is provided atits upper end, with an exterior annular flange a, provided at suitableintervals with openings, and the casing B is of greater diameter thanthe cylinder, and is also provided with an exterior flange b at itslower end provided with openings adapted to register with the openingsof the flange or when the casing is arranged coaxial with the cylinder,as shown in Fig. 1, and bolts 6 pass through the registering openingsand are'engaged by nuts b whereby to secure the casing to the cylinder.

Since the casing is of greater diameter than'the cylinder, a shoulder ais formed between the cylinder and the casing, the said shoulder beingused for a purpose to be presently described. The piston C consists of aring 0, fitting snugly to the cylinder, and a spider c is connected withthe upper edge of the ring, the ring being shouldered as at c, to permitthe connection of the spider therewith. The spider is provided with acentral bearing 0*, in which is threaded the lower end of the piston rod0 and a piston valve .0 engages the top of the ring within the spider,said valve being re tained in place thereby.

The disk D is provided with a central opening cl, through which passesthe piston rod 0, and the edges of the disk are adapted to rest upon theshoulder a before mentioned, when the piston is on the down stroke. Thecasing B is provided with the usual outlet spout 0 and any suitablemeans may be connected with the piston rod for operating the same.

ln operation on the down stroke, the valve D will move down to its seatthrough the weight of the super-incumbent water, while the piston valvewill be raised by the water flowing into the cylinder.

the super-incumbent water, and the water will be lifted by the pistonraising the valve D, and permitting the water to pass into the casingfrom whence it flows through the outlet spout.

It will be evident from the description, that by drawing upward on thepiston, all of the operative parts of the lift may be withdrawn from thewell whereby to clean or repair the same with little trouble and butslight expense. This is of especial advan tage, since it is notnecessary to introduce a separate cylinder into the well, the casing ofthe well acting as a cylinder.

It will be understood that the dimensions shown are not constant but maybe varied in accordance with the end to be attained. In deep water oroil wells, the cylinder will be of very small size and the other membersof the lift reduced in accordance with formulas known to hydraulicengineers. For purposes of irrigation and in shallow wells the cylinderwill be of large size.

I claim:

1. A water lift comprising a cylinder of uniform interior diameterthroughout adapted to be permanently placed in the ground, a cylindricalcasing of greater diameter than the cylinder and attached to the upperend of the cylinder, a piston having a valve lo-' cated in the cylinderand attached to a rod extending through the cylindrical casing, and adisk valve of greater diameter than the cylinder and of less diameterthan the casing arranged in the casing and working loosely on the rod,substantially as described.

2. A water lift comprising a cylinder of uniform interior diameterthroughout adapted to be permanently placed in the ground, an annularflange extending from the upper end of the cylinder, a cylindricalcasing of greater diameter than the cylinder and at- On the up stroke,the piston valve is closed by the weight of tached to the flange, apiston having a valve the red, the disk valve being adapted to seatlocated in the cylinder and fitting closely on the upper end of thecylinder, substan- V therein and attached to a rod extending tially asdescribed.
